Study of Diesel Spray Particle Velocity Field Using a Particle Image Velocimetry Setup

Aim To investigate the spray particle velocity and its distribution characteristics. Methods A set of PIV (particle image velocimetry) system was developed and used to observe and analyze the spray particle velocity field. Results and Conclusion Double exposure image of the spray particle within the region of 10-50 mm from the nozzle tip was recorded and analyzed by the IBAS2000 analysis system. Some characteristics of the spray particle velocity and its distribution were obtained.
